I lived near Miami once upon a time when I was young and good looking.
My suggestion, which might seem to be off the wall a bit, is one weekend to drive (slowly) around a Miami neighborhood that you think you might like to live in.
When you see a guy pushing a mower around the yard, stop and turn off your car, and wave at him. He will be glad to have an excuse to stop mowing for a few minutes. When he does, smile, be friendly, the world needs more of it, tell him you're thinking of moving to the area, and ask him how he likes living in the neighborhood. Trust me, this works. I have stopped mowing many times to answer dumb questions asked by strangers..
You will be surprised how much you can learn about an area from people who actually live there. They will tell you about things you will never find out any other way and may even tell you about Aunt Sally who wants to sell her house and owner-fiance it! That happened to me one time. And you will have just made your first investment of time and effort into finding the right neighborhood to live in and maybe a new neighbor and friend.
If you don't feel comfortable doing what I have suggested in a particular area, keep driving, don't stop, and don't live in that neighborhood. And if you are too shy to do it, you will have to take the advice of those who sell real estate for a living.
All the best,
